the new lugs was the first of the cell organelles to be discovered by scientists. It usually takes up about 10% of the cells volume.
Term
what is current?
Definition
current-this is the rate of flow of electrical charge. charge is a quantity held by electrons, protons and ions. the greater the amount of charge flowing past a point in one second the reader the current. it can be compared to a river current. the current depends on the speed of the river AND the width/depth.
